Another one just back here and all I can say is what an experience this has been! WOW! Thanks to all of you for all the answers, advice, and support. And CONGRATULATIONS to you all!!!
I was thrilled that we decided to do this and even more thrilled to have finished. My time and DH's really surprised me. Sadly I missed the margarita stand opening by 4 minutes.

I hadn't even checked our actual placements until seeing people noted that in this thread. I was so interested in my time I forgot the other stuff.
As for the
Castaway Cay Challenge, that was a lot of fun. Being on the cruise with over 600 other runners, was great. We had something in common with almost everyone we met. The funniest part was the first day or so, watching everyone (myself included) walk funny all over the ship, especially on the stairs. Boy was I tight! Doing the 5K on Wednesday really helped get me back to normal though.
With that said I'm not sure If I would do another full marathon. I'm saying no now but I know how easy it is to get swept up in the excitement so who knows what will happen. I used to say I'd never do a full marathon and look at me now...a marathoner!

Never say never!
